` the same.

This invention relates to valve operating floats, such as are usually employed in the tiush tanks of water-closets, and the objectthereef is to provide a valve operating float ot this class which is composed of sheet metal which will not corrode, rust or be injurimisly atlected by water, acids or the like, andthe separate parts of which arc made in such manner as toforni a perfectly air-tight and water-tight joint without the use ot solder or similar material, and the said invention relates particularly to the construction ot' the float and the method of connecting the valve operating rod therewith..

The invention is fully disclosed in the tollowing specification, ot' which the accenni-a nying drawing forms a part, in which the separate parts of my improvement are dcs.

iguated bysuitable reference characters in each ot' the views, and in which;--

`Figure l is a sectional side view showing myv improved valve operating float, and showing the method of connecting the valve operating rod therewith, Fig'. Q a view similar to Fig. l but showingonly a part of the float and showing the spud or coupling de vice which connects the walvcrodwtlrthc float, and showing one step in the operation ot' connecting` said va lvc rodwith the float1 and ;-l"i'gs. and 4 views similar to Fig. 2 but omitting the spud or coupling device, and showing ditl'erent steps in the process oi' connect-ing the valve rod with the float.

ln the drawing forming part of this specification, I have shown at a a hollow 'spherical valve ioat of the class specied,said float being composed -of sheetinetal which will not corredo, rust or be injuriously affected by water or acids, copper being preferably employed.

rl`he float a, as shown, is composed of two semi-spherical parts o2, each of which is provided at its perimeter with a liangeor rim of. The flange or rim a3 on one part of the loat is wider than the other, and in practice the separate parts of the float are placed together and the-edgeof the wider llange or rim a3 is folded around andcfnnpressed on the edge of the narrower flange or rim a, after which the outer part c* of the flanges or rims fr is olded over into the' position shownl at oF in Fig. 1,',and this method of' connecting the separate parts a ofthe float forms a joint which isboth air-tight .and water-tight, and the tianges a in the process ot folding the same as' above described being also firmly presL-ed together. vide a spud or coupling device I) by means ot which the valve .operating rod c connected with the that, and the coupling de vice o is also composed of metal which will not corrode or rust or be injurously atfected bywvatcr or acids, and said coupling device is provided at one end with a screw threaded socket b2 adapted to receive the rod c, and in the opposite end with a socket, recess or chamber L forming a thin )rejecting flange or rim L* around the base o which is an annular collar or flange lf'. One part of the lloat is provided centrally thereof with an opening d through which, in connecting the coupling device b with the oat, the part b4V ol the coupling device is passed, and placed around said opening and on the. inner side of the part u2 of the float in which said opening is formed is an annular washer e, the diameter ol' which is greater than the diame'- tcr of said opening, and said waz-:her is also composed of in'elal which will not co'rrode, rust or be injuriously affected by water, acids and the like. and in practice, the edge portion ot' the float member around said opening is `t'olded inwardly and around the Washer c asclearly shown at u in Fig/5.1, 2 and :i after which the tiange or rim toi-nn ing the part b* ot' the Spud or coupling device fris egipanded or 4sprung out over `the parts e and a and tirnily compressed thereon as clearly shown in Fig. l, and this operation securely binds the float, vthe coupling device Z) and the annular washer e together and forms a perfectly air-tight and .water-tight connection.

It will be understood that the washer c may beconnected with the part o2 of the float as shown in Figui before the operation oi 'connecting the eoupliug'device o there-l with, and it Will also be understood that in both ofthese'operatious the ,separate parts are put under great pressure so as to press -them tirinly together, and thisl operation Patented Bee.. i228, talig.

also prolos forms a reinforced, st-ifened and smoothr rounded connection or coupling between the float andthe device for connecting the iioat with vthe rod o and when the parts are connected in this mannerthe Heat cannot be detached from the coupling device b Without destroying the foat, or1that part thereof 'with lWhich said. coupling device isv connected.

lIt will also be understood that the coupling devic'eb is connected With one part a2 of the float beforer the separate parts of the float are connected. In practice the rod c is connected With the valve which controls the flow of Water into the tiush tank in the ordinary manner, and the rise and fall ofv the float inthe tank occasioned by the rise and fallof the Water therein operates the valve in the usual manner, but said valve and tank form no part of this invention and l are therefore not shown and described.

`connecting device bein .being composed of two4 parts, one of which 71s provided in one side thereof with any apen.

ture, and a rod connecting device having an annular flange or rim adapted to be passed inwardly through said aperture, said rod' annular flange or rim a apted to bear on the vouter side of the float, and an annular Washer placedon the inner side of the oat and inclosing said aperture and of greater diameter than. said aperture and over and around which the material of the ftoat around said aperture is folded to form a flange which overlaps said Washer on the inner side of the ioat',l and the flange or rim of the connecting device which is passed inwardly through Said aperture being expanded and folded over and' compressed on said annular Washer and over the fiange or rim of the float Which-incloses said washer on the inner side, so as to form a reinforced, smooth and rounded connection or joint between the float and the rod connecting device. l

-In testimony that I claim the foregoing as my invention I have signed my name in presence of the subscribing' Witnesses this 18th day of April 19,08.
